So with the man who has daily inured himself to habits of concentrated attention, energetic volition, and self-denial in unnecessary things. He will stand like a tower when everything rocks around him, and when his softer fellow-mortals are winnowed like chaff in the blast.

The history of philosophy is to a great extent that of a certain clash of human temperaments.

We can change our circumstances by a mere change of our attitude.

This life is worth living, we can say, since it is what we make it.

With mere good intentions hell is proverbially paved.

All the qualities of a man acquire dignity when he knows that the service of the collectivity that owns him needs them. If proud of the collectivity, his own pride rises in proportion. No collectivity is like an army for nourishing such pride.

Pretend what we may, the whole man within us is at work when we form our philosophical opinions.
